We select the symbol of '<' if we assume temporarily for 4x+3 12.
Assume temporarily for 4x+3 12, we select the symbol of '<' because the real equation is "4X+3>12" in which the symbol '>' is used. The symbol '>' is used to show the greater number and a smaller number. The pointed side shows that the number is smaller.
while on the other hand, the wider part shows that the number or value is greater than the other one so we can conclude that we select the symbol of '<' if we assume temporarily for 4x+3 12.

The city of Los Angeles released 96 million "shade balls" into the Los Angeles Reservoir. These will serve to shield the water from the sun's heat in order to reduce evaporation and prevent algal and bacterial growth so no toxic substances are produced in the water. The balls reduce evaporation by 85%-90% so will save a lot of water yearly.
